Abstract

a invenção se refere a um aço inoxidável martensítico caracterizado por sua composição consistir em, em porcentagem em peso: 0,10% = c = 0,45%; traços = mn = 1,0%; traços = si = 1,0%; traços = s = 0,01%; traços = p = 0,04%; 15,0% = cr = 18%; traços = ni = 0,50%; traços = mo = 0,50%; traços = cu = 0,50%; traços = v = 0,50%; traços = nb = 0,03%; traços = ti = 0,03%; traços = zr = 0,03%; traços = al = 0,010%; traços = o = 0,0080%; traços = pb = 0,02%; traços = bi = 0,02%; traços = sn = 0,02%; 0,10% = n = 0,20%; c + n = 0,25%; cr + 16 n ? 5 c = 16,0%; preferencialmente, 17 cr + 500 c + 500 n = 570%; sendo que o restante é constituído por ferro e impurezas resultantes da produção. a invenção também se refere a um método para a produção de um produto semiacabado do aço inoxidável martensítico mencionado anteriormente e uma ferramenta de corte produzida a partir do dito produto semiacabado.The invention relates to a martensitic stainless steel characterized in that its composition consists of, by weight percentage: 0.10% = c = 0.45%; dashes = mn = 1.0%; dashes = si = 1.0%; dashes = s = 0.01%; dashes = p = 0.04%; 15.0% = cr = 18%; dashes = ni = 0.50%; dashes = mo = 0.50%; dashes = cu = 0.50%; dashes = v = 0.50%; dashes = nb = 0.03%; dashes = ti = 0.03%; dashes = zr = 0.03%; dashes = al = 0.010%; dashes = o = 0.0080%; dashes = bp = 0.02%; dashes = bi = 0.02%; dashes = sn = 0.02%; 0.10% = n = 0.20%; c + n = 0.25%; cr + 16 n? C = 16.0%; preferably 17 cr + 500 c + 500 n = 570%; the remainder being iron and impurities from production. The invention also relates to a method for producing a semi-finished product of the aforementioned martensitic stainless steel and a cutting tool produced from said semi-finished product.
